Learn the First Come First Serve (FCFS) disk scheduling algorithm in this 13-minute operating systems tutorial. Explore how this fundamental disk scheduling technique processes disk I/O requests in the order they arrive, understanding its implementation, advantages, and limitations. Discover the algorithm's straightforward approach to managing disk access requests, examine practical examples demonstrating how FCFS handles multiple disk requests sequentially, and analyze its performance characteristics including average seek time calculations. Master the concepts through step-by-step explanations of how the disk head moves to service requests in chronological order, compare FCFS with other disk scheduling algorithms, and understand when this algorithm is most appropriate in real-world operating system scenarios.
